19.5" wheels for 8-lug x 6.5" bolt pattern?

It is my personal theory that I've been suggesting on here for a while now.
Got to be careful because some vans had a d60 in them and not the 10.5"
The 4x4 vans I would assume use the same bolt pattern as the rear, so that would make it the old bolt pattern.
I've seen a number of 4x4 vans, but never had a tape measure to verify.

I wonder if any parts stores would have a 4x4 van front hub in stock to measure.

For the rear you may be able to use an OBS 10.25" hub and a van rear rotor.

I knew the semi-floating rear axle was a d60 but when I see a full float srw van it really looked bigger like a 10.5

Thanks for the response(s). Unfortunately- I live in a somewhat remote part of Alaska and am reluctant to order a bunch of heavy iron w/out knowing for sure that it will work. I've done a fair amount of searching on web forums and have found no workarounds to put 8-6.5's on metric hubs without,
1) welding and redrilling the rims, or
2) using adapters.
I spoke with Fred at WheelAdapters.com, he indicated that adapters could not be safely used because the hole in 8-6.5 Ford rims is smaller than in the metric rims, and so would have to be machined.

Hold off a little while then.
I'm putting in a drw dana70 into my superduty soon. And I'll be looking to match the front wheel pattern. I'll do some leg work and try to figure it out for sure.
I'll post a new thread with the results.
